Three launches, two recoveries, two coasts

Just over two weeks ago, SpaceX accomplished its most impressive feat of cadence yet, both launching and recovering two separate Falcon 9s in approximately 49 hours.

Two weeks later and two days after conducting a third launch in 13 days, residents of Los Angeles, California and Cape Canaveral, Florida both coincidentally reported that the two recovered boosters from the previous two launches had both gone horizontal and appeared ready for transport. After docking in Port Canaveral for the second time, Core 1029 was seen entering SpaceX’s LC-39A integration facilities on Friday. The booster on the West coast, 1036, was loaded aboard one of the company’s converted Falcon 9-carrying semi-trucks, likely for transport to SpaceX’s Hawthorne manufacturing facilities, or possibly on a direct route to McGregor, Texas for refurbishment and testing.

This is exciting for several reasons. Foremost, 1036 is a likely candidate for reuse, and SES-10 sets a firm precedent for this. The first commercial reuse of an orbital-class launch vehicle, Falcon 9’s second stage and SES-10 payload launched on a first stage that had flown five months before during the successful launch of Iridium’s first ten NEXT satellites.

Given the potential impact of failure on the adoption of reuse as a commercial standard, SpaceX likely approached the refurbishment of the vehicle with an end-goal balanced between perfection and realism. The orbit of Iridium’s NEXT constellation is the reason the booster was chosen for the first operational reuse: their low Earth polar orbits require Falcon 9’s first stage to undergo a smaller amount of heating and general hypersonic battering when compared with SpaceX’s more common commercial launches of geostationary satellites.

A sound example of the extremes of Falcon 9’s suborbital reentry heating can be found in the recovery of 1029, which launched BulgariaSat-1 to a supersynchronous transfer orbit. Noted before the launch by Musk over his favored medium, 1029’s recovery was expected to be the most energetic yet, and thus success was less than certain. The results of this additional heating were obvious, and keen observers rapidly noted that the most stressed of 1029’s aluminum grid fins appeared to be considerably deformed from the stage’s energetic return to OCISLY, completed melted through in places. Considering the debut of more robust titanium grid fins aboard the launch of Iridium-2 only two days later, the quasi-destruction of one of 1029’s grid fins was somewhat fitting. 1036’s titanium grid fins looked barely worse for wear after a landing that was also deemed aggressive due to Just Read The Instructions having to avoid bad weather just before the landing.

Stirring explorations of the limits of recovery aside, both boosters are now ready to be examined and refurbished ahead of one or even two additional launches. SpaceX’s willingness to use the booster recovered from the launch of Thaicom-8 has already established that the company has a certain level of confidence in the reuse of first stages that have suffered high-velocity recoveries. Thus, 1036 is nearly certain to be reused, and 1029 has a strong chance as well.

The hot recovery of 1029 further marked the first use of a remotely-operated recovery robot aboard OCISLY, and could be seen below the leaning first stage as it entered Port Canaveral. It appears that its first use was a success, and the robot will certainly have a busy future of remotely securing first stages after landing. Remote securing and safing will both improve safety for those directly involved in on-ocean recovery, but it is also intended to expedite the process in order to ensure that OCISLY is prepared to recover Falcon 9 as often as possible. SpaceX’s recent cadence accomplishment of three launches in 13 days drives home the reality that weekly launches are readily achievable for the company, so long as there are pads available and payloads to be launched.

Weekly recoveries for an ASDS like OCISLY would be extremely time-sensitive, given the need for at least several days to simply reach the point of landing in the Pacific, and the addition of rapid robotic alternatives for operations aboard the drone ships could make such a goal more achievable. With SpaceX’s land-based landing facilities in perspective, it is easier to imagine a close future with weekly launches and landings of both Falcon 9 and Falcon Heavy, and possibly the propulsive-landing Dragon 2 spacecraft further down the road.

A symbiosis of SpaceX fans and those familiar with the metal and chemistry have also led to fans speculating that the now-standard titanium grid fins may develop a subtle, golden patina of oxygenation after many reuses. Nothing could be more picturesquely symbolic of the successes SpaceX has had in their pursuit of reusable rocketry.

Tesla teases new market entrance with confusing and cryptic message

Tesla teased its entrance into a new market with a confusing and what appeared to be cryptic message on the social media platform X.

The company has been teasing its entrance into several markets, including Africa, which would be a first, and South America, where it only operates in Chile.

In September, Tesla started creating active job postings for the Colombian market, hinting it would expand its presence in South America and launch in a new country for the first time in two years.

Tesla job postings seem to show next surprise market entry

The jobs were related to various roles, including Associate Sales Manager, Advisors in Sales and Delivery, and Service Technicians. These are all roles that would indicate Tesla is planning to launch a wide-scale effort to sell, manage, and repair vehicles in the market.

Last night, Tesla posted its latest hint, a cryptic video that seems to show the outline of Colombia, teasing its closer than ever to market entry:

This would be the next expansion into a continent where it does not have much of a presence for Tesla. Currently, there are only two Supercharger locations on the entire continent, and they’re both in Chile.

Tesla will obviously need to expand upon this crucial part of the ownership experience to enable a more confident consumer base in South America as a whole. However, it is not impossible, as many other EV charging infrastructures are available, and home charging is always a suitable option for those who have access to it.

Surprisingly, Tesla seems to be more concerned about these middle-market countries as opposed to the larger markets in South America, but that could be by design.

If Tesla were to launch in Brazil initially, it may not be able to handle the uptick in demand, and infrastructure expansion could be more difficult. Brazil may be on its list in the upcoming years, but not as of right now.

Tesla expands crucial Supercharging feature for easier access

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Tesla has expanded a crucial Supercharging feature that helps owners identify stall availability at nearby locations.

Tesla said on Tuesday night that its “Live Availability” feature, which shows EV owners how many stalls are available at a Supercharger station, to Google Maps, a third-party app:

Already offering it in its own vehicles, the Live Availability feature that Teslas have is a helpful feature that helps you choose an appropriate station with plugs that are immediately available.

A number on an icon where the Supercharger is located lets EV drivers know how many stalls are available.

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Essentially, when those drivers needed to charge at a Supercharger that enables non-Tesla EVs to plug in, there was a bit more of a gamble. There was no guarantee that a plug would be available, and with no way to see how many are open, it was a risk.

Tesla adding this feature allows people to have a more convenient and easier-to-use experience if they are in a non-Tesla EV. With the already expansive Supercharger Network being available to so many EV owners, there is more congestion than ever.

This new feature makes the entire experience better for all owners, especially as there is more transparency regarding the availability of plugs at Supercharger stalls.

It will be interesting to see if Tesla is able to expand on this new move, as Apple Maps compatibility is an obvious goal of the company’s in the future, we could imagine. In fact, this is one of the first times an Android Auto feature is available to those owners before it became an option for iOS users.

Apple owners tend to get priority with new features within the Tesla App itself.

Elon Musk’s Boring Co goes extra hard in Nashville with first rock-crushing TBM

The Boring Company’s machine for the project is now in final testing.

The Boring Company is gearing up to tackle one of its toughest projects yet, a new tunnel system beneath Nashville’s notoriously tough limestone terrain. Unlike the soft-soil conditions of Las Vegas and Austin, the Music City Loop will require a “hard-rock” boring machine capable of drilling through dense, erosion-resistant bedrock. 

The Boring Company’s machine for the project is now in final testing.

A boring hard-rock tunneling machine

The Boring Company revealed on X that its new hard-rock TBM can generate up to 4 million pounds of grip force and 1.5 million pounds of maximum thrust load. It also features a 15-filter dust removal system designed to keep operations clean and efficient during excavation even in places where hard rock is present.

Previous Boring Co. projects, including its Loop tunnels in Las Vegas, Austin, and Bastrop, were dug primarily through soft soils. Nashville’s geology, however, poses a different challenge. Boring Company CEO and President Steve Davis mentioned this challenge during the project’s announcement in late July.

“It’s a tough place to tunnel, Nashville. If we were optimizing for the easiest places to tunnel, it would not be here. You have extremely hard rock, like way harder than it should be. It’s an engineering problem that’s fairly easy and straightforward to solve,” Davis said.

Nashville’s limestone terrain

Experts have stated that the city’s subsurface conditions make it one of the more complex tunneling environments in the U.S. The Outer Nashville Basin is composed of cherty Mississippian-age limestone, a strong yet soluble rock that can dissolve over time, creating underground voids and caves, as noted in a report from The Tennessean.

Jakob Walter, the founder and principal engineer of Haushepherd, shared his thoughts on these challenges. “Limestone is generally a stable sedimentary bedrock material with strength parameters that are favorable for tunneling. Limestone is however fairly soluble when compared to other rack materials, and can dissolve over long periods of time when exposed to water. 

“Unexpected encounters with these features while tunneling can result in significant construction delays and potential instability of the excavation. In urban locations, structures at the ground surface should also be constantly monitored with robotic total stations or similar surveying equipment to identify any early signs of movement or distress,” he said.
